Unfriend people who do not post to Facebook or engage with anyone else. You'll find your posts start getting reach they never did before. Why? Facebook only releases your posts to a few people at first and watches what they do with it.

The people who can step up my experience are those who have a common set of experiences with people I know. Think about it. How often did a total stranger come into your life to make your evening better? Not very often. But the friend of your friend? That happens all the time.
